ELECTRIC STORAGE BATTERY.

Application mea necember'zv, 1919. serial No. 347,767.

To all whom t may concer/n.'

Be it known that I, FREDERICK W. RADELL, a citizen of the United States, residing at Glenside, county of Montgomery, State of Pennsylvania,- have invented a new and useful Electric Storage Battery,A of which the following is a specification.

My invention-relates to an improvement in an electric storage battery and consists of means whereby the separators for the grid plates employed are prevented from shifting vertically and laterally.

The invention is satisfactorily illustrated in the accompanying drawing, but the important instrumentalities thereof may be varied, and so it is to be understood that the invention is not limited to the specific details shown and described, as long as they are within the spirit or scope of the claims.

Figures 1 and 2 represent vertical sections of an electric storage battery embodying my invention.

Fig. 3 represents a top or plan view of a portion thereof.

Fig. 4 represents a side elevation of a portion thereof on an enlarged scale.

Fig. 5 represents a top or plan view thereof on an enlarged scale.

Fig. 6 represents a vertical section portion thereof on an enlarged scale.

Figs. 7 and 9 represent side elevations respectively of modifications.

Fig. 8 represents a top or plan View of `of a the modification shown in Fig. 7.

Fig. 10 represents a top or plan view of the modification shown in Fig. 9.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings.

1 designates the grid plates of an electrical storage battery which excepting the features of my invention applied thereto are well known in the art.

Projecting upwardly from the tops of said plates are the pairs of lips 2, the members of each of which are spaced apart prming between them the space 3, see

4 designates bars interposed between adjacent plates for separating the latter. These bars are bifurcated consisting of legs 5 and crowns 6, the latter uniting the tops of the legs, and said legs straddling vthe respective plates andsaid crowns being seated on the tops of the bars in the space 3 thereon and being embraced laterally by the lips 2.

The upper ends forming inwardly projecting shoulders 7 which overhang and engage the upper 4sides of the crowns of the separating bars, see Fig. 4, and so serve to interlock said crowns and consequently the bars 4 against rising and vertical displacement from the grid plates. Then the lips control said crowns and consequently the bars from lateral shifting on the grid plates, and so the bars retain their positions whereby the grid plates preserve their spaced positions in the battery casing or jar.

In Figs. 7 and .8 I show a cross head 8 which is provided with legs 9, said cross head being adapted to rest upon the crown of the separating bar 4 and said legs being pinched or driven tightly into the upper ends of the grid plates, thus holding said cross head and consequently the bar 4 tightly on the grid plate.

In Figs. 9 and 10 I show studs 10 rising from the bar and entering the cross head 11 and being upset or riveted on said cross head, thus retaining the latter in place on the crown of the bar 4 and consequently controlling the separating bar from shifting or displacement as in the other constructions.

Interposed between the grid plates are sheets 12 of perforated Celluloid, or other suitable material.

Having thus described my `invention what I claim as new anddesire to secure by Letters Patent, is

1. In -an electric storage battery, grid plates and a separating barvfor the latter, and means on the respective plates for retaining positively said Abar in set positionl thereon.

2. In an electric storage battery, grid plates, separating bars for the latter, said bars being adapted to be fitted on saidl plates and upwardly extending members on the said plates adapted to engage positively ladjacent portions of the respective bar and thereby prevent vertical and lateral shifting of the latter.

3. In an electric storage battery, grid plates, and a separating bar for the latter, said bar having a crown by which it is adapted to be supported on the respective plate, said plate being provided with means v of said lips are upset- :ulaplwl to engage positively said crown to prevent lxsplaeement of Saul bar.

4. ln an eleetrlc storage battery, a separatinghar furthe grid plates thereof. said har living nl' the vform of a biflufcation, its legs being; :ulaptetl to stradtlle the respective plate. and having a crown which is adapted to be supported 011 said plate, and means 011 the latter adapted to engage positively saicl crown and prevent vertical aml lateral 10 slxli'tmg of the bar.
